Table 1: show oam ethernet connectivity-fault-management mep-database Output Fields

Field Name

Field Description

Maintenance domain name

Maintenance domain name.

Format (Maintenance domain)

Maintenance domain name format configured.

Level

Maintenance domain level configured.

Maintenance association name

Maintenance association name.

Format (Maintenance association)

Maintenance association name format configured.

Continuity-check status

Continuity-check status.

Interval

Continuity-check message interval.

MEP identifier

Maintenance association end point (MEP) identifier.

Direction

MEP direction configured.

MAC address

MAC address configured for the MEP.

Auto-discovery

Whether automatic discovery is enabled or disabled.

Priority

Priority used for CCMs and linktrace messages transmitted by the MEP.

Interface name

Interface identifier.

Interface status

Local interface status.

Link status

Local link status.

Remote MEP not receiving CCM

Whether the remote MEP is not receiving CCMs.

Erroneous CCM received

Whether erroneous CCMs have been received.

Cross-connect CCM received

Whether cross-connect CCMs have been received.

RDI sent by some MEP

Whether the remote defect indication (RDI) bit is set in messages that have been received. The absence of the RDI bit in a CCM indicates that the transmitting MEP is receiving CCMs from all configured MEPs.

CCMs sent

Number of CCMs transmitted.

CCMs received out of sequence

Number of CCMs received out of sequence.

LBMs sent

Number of loopback messages (LBMs) sent.

Valid in-order LBRs received

Number of loopback response messages (LBRs) received that were valid messages and in sequence.

Valid out-of-order LBRs received

Number of LBRs received that were valid messages and not in sequence.

LBRs received with corrupted data

Number of LBRs received that were corrupted.

LBRs sent

Number of LBRs transmitted.

LTMs sent

Linktrace messages (LTMs) transmitted.

LTMs received

Linktrace messages received.

LTRs sent

Linktrace responses (LTRs) transmitted.

LTRs received

Linktrace responses received.

Sequence number of next LTM request

Sequence number of the next linktrace message request to be transmitted.

1DMs sent

If the MEP is an initiator for a one-way ETH-DM session: Number of one-way delay measurement (1DM) PDU frames sent to the peer MEP in this session.

For all other cases, this field displays 0.

Valid 1DMs received

If the MEP is a receiver for a one-way ETH-DM session: Number of valid 1DM frames received.

For all other cases, this field displays 0.

Invalid 1DMs received

If the MEP is a receiver for a one-way ETH-DM session: Number of invalid 1DM frames received.

For all other cases, this field displays 0.

DMMs sent

If the MEP is an initiator for a two-way ETH-DM session: Number of Delay Measurement Message (DMM) PDU frames sent to the peer MEP in this session.

For all other cases, this field displays 0.

DMRs sent

If the MEP is a responder for a ETH-DM session: Number of Delay Measurement Reply (DMR) frames sent.

For all other cases, this field displays 0.

Valid DMRs received

If the MEP is an initiator for a two-way ETH-DM session: Number of valid DMRs received.

For all other cases, this field displays 0.

Invalid DMRs received

If the MEP is an initiator for a two-way ETH-DM session: Number of invalid DMRs received.

For all other cases, this field displays 0.

Remote MEP identifier

MEP identifier of the remote MEP.

State (remote MEP)

State of the remote MEP: idle, start, ok, or failed.

MAC address

MAC address of the remote MEP.

Type

Whether the remote MEP MAC address was learned using automatic discovery or configured.

Interface

Interface of the remote MEP. A seven-digit number is appended if CFM is configured to run on a routing instance of type VPLS.

Last flapped

Date, time, and how long ago the remote MEP interface went from down to up. The format is Last flapped: year-month-day hours:minutes:seconds timezone (hours:minutes:seconds ago). For example, Last flapped: 2002-04-26 10:52:40 PDT (04:33:20 ago).

Remote defect indication

Whether the remote defect indication (RDI) bit is set in messages that have been received or transmitted.

Port status TLV

  • In the Maintenance domain section, displays the last transmitted port status TLV value.

  • In the Remote MEP section, displays the last value of port status TLV received from the remote MEP.

    In the Action profile section, displays, the last occurred event port-status-tlv blocked event. This event occurred due to the reception of blocked value in the port status TLV from remote MEP.

Interface status TLV

  • In the Maintenance domain section, displays the last transmitted interface status TLV value.

  • In the Remote MEP section, displays the last value of interface status TLV received from the remote MEP.

    In the Action profile section, if displays, the last occurred event interface-status-tlv event ( either lower-layer-down or down). This event occurred due to the reception of either lower or down value in the interface status TLV from remote MEP.

Action profile

Name of the action profile occurrence associated with a remote MEP.

Last event

When an action profile occurs, displays the last event that triggered it.

Last event cleared

When all the configured and occurred events (under action profile) are cleared, then the action taken gets reverted (such as down interface is made up) and the corresponding time is noted and displayed.

Action

Action taken and the corresponding time of the action occurrence.
